  • Patent number: 11307182
    Abstract: A system for determining isotopic composition of a gaseous sample. The system includes at least one gas chromatograph for separating the gaseous sample into gaseous components. Furthermore, the system includes a combustion furnace operatively coupled with the at least one gas chromatograph for oxidizing the gaseous components. Moreover, the system includes a water separator operatively coupled with the combustion furnace. Furthermore, the system includes an isotope-ratio mass spectrometer operatively coupled with the water separator. Moreover, the isotope-ratio mass spectrometer comprises an ion source for generating ion beams associated with each of the oxidized gaseous components and a mass analyser for receiving the generated ion beams from the ion source, wherein the mass analyser is operable to determine isotopic concentrations associated with each of the ion beams.

  • Patent number: 9308970
    Abstract: A momentum altering system comprises a transportation device configured to transport the momentum altering system towards an object moving through water. An engagement device is configured to attach to the object when the momentum altering system is transported sufficiently near the object. At least one decelerating device is connected to the engagement device. At least one decelerating device is deployed by the engagement device after the engagement device attached to the object. At least one decelerating device includes a plurality of parachute sea anchors that produce drag when pulled though water thereby altering momentum of the object.
